STA10 Ubuntu 8.04 64 bit GNU/Intel Compilers: core dump during test

Hello All,

Related to another thread of mine in which I´m attempting to install STA10 using Intel compilers only, I´m also attempting an install with both GNU and Intel on Ubuntu 8.04 64bit. The installation goes well, but a number of the long tests show core dumps:

>warning: Can't read pathname for load map: Input/output error.
>Core was generated by `./asteru Python/Execution/E_SUPERV.py -eficas_path ./Python -commandes >fort.1 -'.
>Program terminated with signal 11, Segmentation fault.

The setup.log and files with traceback are attached. An internet search hasn´t come up with anything.

Does anyone have a clue or suggestions where I can start looking to solve this?

Many thanks for your time.

Cheers

Gary

Re: STA10 Ubuntu 8.04 64 bit GNU/Intel Compilers: core dump during test

Hi,

This is a strange crash. Looks like a bug in the way we call the LAPACK library though we have no such problem here with the MKL library also.

Could you try to compile a separate executable using ASTK and the "SURCHARGE" (or "DEVELOP" in english) tab. You just have to point to the fortran files attached to this post in the upper part and add an entry of type "exec" in the lower part (with the R case ticked). Then click "run". It will build the exectuable.

Then you should run the faulty test case (here sdld27a) with the freshly built exec (this time make sure the D case is ticked only in the "DEVELOP" tab).

In the attached archive are a few fortran files :

desoza@claut621:~/Bureau/sdld27a$ ls -lR To_try
To_try:
total 8
drwxr-xr-x 2 desoza desoza 4096 2009-08-26 09:17 F_1st
drwxr-xr-x 2 desoza desoza 4096 2009-08-26 09:17 F_2nd

To_try/F_1st:
total 4
-rw-r--r-- 1 desoza desoza 2061 2009-08-26 09:15 xerbla.f

To_try/F_2nd:
total 104
-rw-r--r-- 1 desoza desoza 49465 2009-08-26 09:21 op0045.f
-rwxr-xr-x 1 desoza desoza 41782 2009-08-26 09:24 vpqzla.f
-rw-r--r-- 1 desoza desoza  2061 2009-08-26 09:15 xerbla.f

You should try first to build an executable only with the Fortran files in F_1st directory, and then (if it still fails), try to build another executable with the Fortran files in the second directory.

Hi Thomas,

I tried both options and unfortunately neither work. Both abort with the same core dump tracebacks. Interestingly all the long test runs that don´t fail with errors end with Alarm.

Thanks and regards

Gary

PS Compiling these patches only took about 15s each, not the usual 45 minutes to compile Aster. I assume this is correct.

Re: STA10 Ubuntu 8.04 64 bit GNU/Intel Compilers: core dump during test

Hi Gary,

Thanks for the feedback. Does it really yield the same core dump and traceback ? If so, one thing you could try is changing the BLAS/LAPACK libraries (e.g replacing the Intel MKL with standard implementations). Just use the packages that come with your distribution.

Re: STA10 Ubuntu 8.04 64 bit GNU/Intel Compilers: core dump during test

Hi Thomas,

I´m pretty happy with my installation as I only get 12 errors. The attached summary document shows which tests fail and a brief description of why they fail. I´ve also included the following result files:

sdld27a.o.baseline -> result from my compilation (from standard setup.cfg)
sdld27a.o-try-1      -> results when using executionable for try1
sdld27a.o-try-2      -> results when using executionable for try2

Out of interest I´ve also compiled using GCC only and GCC+Intel. These result in more errors/NOOK_TEST_RESU than Intel only. I can send you the error details if you need them.

I´m happy to close this thread unless you´d like me to put more time into investigating these errors?

Thanks for your help.

Regards

Gary

Sure. Thanks for the feedback. Have fun with Aster !
